The Main Classification of Artificial Abrasive Grit

Artificial abrasive grit products are mainly divided into two categories: corundum abrasive grit and silicon carbide abrasive grit.

Specifically, there are basically the following abrasive products that can be provided by China abrasive manufacturers:

1. Brown corundum abrasive grit, whose main component is Al₂O₃, has the characteristics of medium hardness, high toughness, sharp particles and relatively low price. It is suitable for processing metals with high tensile strength. Both microcrystalline corundum abrasive grit and black corundum abrasive grit are the derived varieties of brown corundum abrasive grit.

2. The hardness of white corundum abrasive grit is slightly higher than that of brown corundum. However, its toughness is poor. It is easy to cut into the workpiece during grinding. Its self-sharpening property is good, and its heat generation is small. It has strong grinding ability and high efficiency. The chromium corundum abrasive grit is its derived variety.

3. Single crystal corundum abrasive grit, whose particles are composed of single crystals, has good multi-edge cutting edges. In addition to its higher hardness and toughness, it also has strong grinding ability, and less grinding heat. The disadvantage of this abrasive grit is that since it has higher production costs but lower output, the price of it is relatively high. Zirconium corundum abrasive grit is also a crystalline compound, with slightly lower hardness, finer crystal size and good wear resistance.

4. Black silicon carbide abrasive grit, green silicon carbide abrasive grit, cubic silicon carbide abrasive grit, and cerium silicon carbide abrasive grit all belong to silicon carbide abrasive grit. The main component of silicon carbide abrasive grit is silicon carbide SiC, which has high hardness, high brittleness, sharp abrasive grains, good thermal conductivity, and strong wear resistance. Therefore,  these previously mentioned abrasive grits are all more suitable for processing hard and brittle metal and non-metal products.

The silicon carbide abrasive grits are suitable for surface deburring, chamfering, descaling and surface polishing of machinery, electronics, metal parts, hardware, tools, auto parts, instrumentation, casting, medical treatment, craft jewelry, and other industries.

In conclusion, as for abrasives that belong to silicon carbide abrasive grit, their grinding efficiency is high, and they are also wear-resistant and durable. It is not easy for them to get stuck, and the surface brightness of the silicon carbide abrasive grit is high!
